Urban Flooding and Sponge Cities

 Group photoDSC_0118DSC_0174

On 3-5 July 2017, the UK-China Joint Workshop on Urban Flooding and Sponge Cities was held in Shenzhen. The workshop was aimed at early career researchers from two countries to enable networking and sharing of research findings in sustainable urban water management. The workshop was funded by the British Council, the National Natural Science Foundation of China (NSFC) and EPSRC (via the BRIM project), and was organised by Professor Dragan Savić FREng, Professor Guangtao Fu, and Dr Albert Chen (University of Exeter), on the UK side, and the Chinese partners led by Professor Yuntao Guan and Professor Haifeng Jia (Tsinghua University) and Professor Huapeng Qin (Peking University).

The workshop provided a platform for researchers, urban planners and engineers to discuss critical issues and main challenges, share the latest research outcomes, and demonstrate the best practices in flood risk management and Sponge City developments. Over 40 participants from the UK, China, Canada, Japan, South Korea and Sri Lanka attended the workshop and presented a wide range of methodologies and applications, including flood simulation and risk assessment tools, new and emerging metrics, and frameworks that can be used for design, planning and assessment of sponge cities. Few distinguished experts in the field, including Paul Leinster (Cranfield University), Nigel Wright (De Montfort University), Sarah Bell (University College London), Janaka Ruwanpura (University of Calgary) and Mooyoung Han (Seoul National University), also delivered keynote talks during the workshop.
